The principle of mobile phone vibration

The principle of mobile phone vibration, the most common is the ordinary small motor, the head is equipped with a cam, and the center of gravity of the cam is not in the center of the rotating shaft. When it rotates, the cam moves in a circle and produces centrifugal force. Because the direction of centripetal force changes with the rotation of the cam, the mobile phone in hand feels vibrating.

In addition, combined with the circuit of the mobile phone, when receiving information and needing to be awakened by vibration, the control circuit of the mobile phone will send out a signal, so as to input an appropriate current to the motor, and the rotor of the motor rotates to drive the cam to rotate, thereby generating vibration. According to different signals and different vibration rhythms, there is vibration.

On the other hand, the principle and structure of the linear motor used by Apple are actually not complicated. There are metal shrapnel inside, a magnet on the top of the two shrapnel, and a coil fixed on the shell. When the coil is energized, the coil and the magnet will generate force, and the magnet in the middle will move back and forth to generate vibration.
